ESD (Electronic Static Discharge) protection structure and method

Abstract

The invention relates to the field of the structure of a display device and manufacturing thereof, in particular to an ESD (Electronic Static Discharge) protection structure and method. In a device manufacturing process, an electrostatic discharge structure is manufactured in an open region during manufacturing of a structural layer having a current conducting property in a device region, and carriers remaining in the device region are discharged circularly to discharge carriers remaining in the device region once in the manufacturing process of each structural layer having the current conducting property in order to prevent the carriers in the device region from being accumulated on a large scale, thereby avoiding the formation of excessive momentary current, effectively lowering the probability of an electrostatic damage phenomenon in the device structure, and improving the performance and yield of a product.

Description

technical field [0001] The invention relates to the structure and preparation field of a display device, in particular to a panel design ESD protection structure and method. Background technique [0002] In the array (Array) process of display devices (such as AMOOLED, etc.), due to the remaining carriers (holes or electrons) in the prepared device structure with conductive properties, and then gather to form static electricity, especially the preparation of the metal layer During the process, redundant carriers are generated in the structural layer that is very easy to prepare, and when the same carriers (that is, both electrons or holes) remain between the interconnected metal layers, the redundant carriers Carriers converge and form a strong electrostatic phenomenon. When encountering a suitable release path, a large number of carriers will be transferred or discharged instantaneously (Electronic Static Discharge, ESD for short), which will cause damage to the internal ci...

Problems solved by technology

[0006] In view of the above-mentioned problems, the present invention provides an ESD protection structure and method to overcome the remaining carriers such as electrons or holes (holes) in the prepared structural devices when performing the array process of the panel in the prior art. ), and a large number of residual carriers of the same type will cause serious electrostatic phenomena, and the residual large number of carriers will move instantaneously when encountering a discharge inducer, causing large currents and electrostatic discharges, and then Severe damage to the device structure, especially the circuit structure in the panel may even be broken down to cause short circuit and / or open circuit of the device, which greatly reduces the performance and yield of the device
